The Five Conceptual Areas of the OSI/ISO Network Management Model

Since its conception on the 23rd of February 1947, the International Organization for Standardization or commonly known as ISO became a major contributor as far as network standardization is concerned. Its network management model is one of the most useful means to understand better the different processes and functions involved in the network management system. The five conceptual areas of the OSI/ISO network management model are the following: (1) Performance Management; (2) Configuration Management; (3) Accounting Management; (4) Fault Management; and (5) Security Management.

As the name implies, performance management’s aim is to provide acceptable and desirable results that the company expects to drive business goals and objectives. In here, measuring the capabilities of each part of the network and making resources available when seem necessary are just some of the activities involved on this level.

The second area, configuration management, deals with monitoring all areas of the network system including system configuration where hardware devices and software applications are tracked to ensure optimum network performance.

Accounting management, on the hand, is all about checks and balances. This means measuring and regulating the parameters of network utilization, in such a way that it will be fairly distributed across all areas of the network system without causing any problems.

When disaster strikes, fault management will take care of it. Such errors may lead to network downtimes and malfunctions, which is the reason why the role of fault management is important to keep users track of possible unexpected changes in the system so that appropriate fix will be provided immediately.

Lastly, security management deals with controlling access rights to certain network resources so as to prevent unauthorized entry to confidential information that are critical to the business.
